Totally agree, and it still doesn’t quite work for me.
What works fine (and is actually somewhat easier) is to commission device directly through the matter server webui.
You’ll need:
- The matter server enabled with bluetooth
- The TRV as displayed in HA Thread integration “info” page
- The pairing code that goes with the device
Et voila, device integrated…
In this process, the matter server basically replaces the phone.
